GAS-HEATER.

Specification forming part of Letters Patent No. 47,426, dated April 25, 1865.

Similar letters of reference indicate correl spending parts in the several figures.

The nature of my invention consists, first, i1 theemployment ot' an inverted conical or otherwise concave-shaped distributing-screen arranged above the gasjet and surrounded by a simple tube in a manner that the iiow ot' gas from the same jet as well as a sur rounding iiow of air are both conducted together to the screen, and there the iiow ot' gas i; deiiected and divided by the point of the inverted conical screen and obliged to distribute over the whole surface of the screen, and thus pierced and mingled by and with the said iiow of air before and while passing through the said screen to the iiaine, whereby a more perfect distribution and supply of oxygen to the gasis had and more perfect combustion and greater heat from the same quailtity ot' gas obtained than with those hereto- Ioge known or used; second, it consists in the peculiar simple construction and arrangement of parts ot' the burner, whereby the manufacture of the same is economized and its liability ot' allowing to light directly at the gas jet and too close to it, which is often the case with those now in use, is entirely removed.

To enable others skilled in the art to make and use my invention, I will proceed todescribe its construction and operation.

A, Fig, l, represents thc body ofthe burner, which is of tubular form, and near to its lower end it is provided with the gas-tube B, as shown in the drawings, or in any other equivalent manner, and in the upper portion it is provided with the distributing-screen C. The

said screen C is preferred to be made of per forated metal of the shape ot' an inverted cone, but may also be `made of wiregauze and of any other considerably concave form. Its top edge is secured to `the tube A by means of a ange, D, tting to a recess, E, formed on the tube A, and by means of an elastic wire ring, F 5 but it may be also secured by means of riveting or other wire attachment of the said top edge or flange, D, to the body or tube A. The gas-tube B is provided with an opening, G, in a vertical central line with the point ot' the inverted cone, so that the gas owing from said opening G will be equally divided and deflected from the point ofthe cone. Thus, in order to supply the gas with the full and proper'amount of oxygen to make complete combustion and toreceive all the amount of heat from the same, it is necessary to furnish the gas with two parts and a halt' ot' oxygen to one part ot'gas, and to perform this eii'ect the ordinary screen now in usc is not suiiiciently powerful enough.

From thetoregoingitmay be clearly seen that tlze gas deiected from the point of the screen G is obliged to distribute over the whole snri'ace of the screen, and to divide and mingle with the air to a great extent, and a large amount of oxygen will be supplied before reaching the point ot' combustion and it will be perceived that by means of the large distance from the gas-jet G to the top end of the tube A in proportion to the area of the tube A, and with regard tothe relative large and concave distributingsnrface of' the screen G,`

the iiame of the burner when in operation is prevented from setting tire to the gas close` at the opening, G, and thereby to destroy its use, which is often the case with the burners -now in use. Also, by having one simple tube,
